SetTimerEx
Description
Sets a timer to call a function after the specified interval. This variant ('Ex') can pass parameters (such as a player ID) to the function.
Name | Description |
---|---|
const functionName[] | The name of a public function to call when the timer expires. |
interval | Interval in milliseconds (1 second = 1000 MS). |
bool:repeating | Boolean (true/false (or 1/0)) that states whether the timer should be called repeatedly (can only be stopped with KillTimer) or only once. |
const specifiers[] | Special format indicating the types of values the timer will pass. |
OPEN_MP_TAGS:... | Indefinite number of arguments to pass (must follow format specified in previous parameter). |
Returns
The ID of the timer that was started. Timer IDs start at 1 and are never reused. There are no internal checks to verify that the parameters passed are valid (e.g. duration not a minus value). Y_Less' 'fixes2' plugin implements these checks and also vastly improves the accuracy of timers, and also adds support for array/string passing.
Examples
SetTimerEx("EndAntiSpawnKill", 5000, false, "i", playerid);
// EndAntiSpawnKill - The function that will be called
// 5000 - 5000 MS (5 seconds). This is the interval. The timer will be called after 5 seconds.
// false - Not repeating. Will only be called once.
// "i" - I stands for integer (whole number). We are passing an integer (a player ID) to the function.
// playerid - The value to pass. This is the integer specified in the previous parameter.
// The event callback (OnPlayerSpawn) - we will start a timer here
public OnPlayerSpawn(playerid)
{
// Anti-Spawnkill (5 seconds)
// Set their health very high so they can't be killed
SetPlayerHealth(playerid, 999999.0);
// Notify them
SendClientMessage(playerid, -1, "You are protected against spawn-killing for 5 seconds.");
// Start a 5 second timer to end the anti-spawnkill
SetTimerEx("EndAntiSpawnKill", 5000, false, "i", playerid);
}
// Forward (make public) the function so the server can 'see' it
forward EndAntiSpawnKill(playerid);
// The timer function - the code to be executed when the timer is called goes here
public EndAntiSpawnKill(playerid)
{
// 5 seconds has passed, so let's set their health back to 100
SetPlayerHealth(playerid, 100.0);
// Let's notify them also
SendClientMessage(playerid, -1, "You are no longer protected against spawn-killing.");
return 1;
}
Notes
warning
tip
Timer ID variables should be reset to 0 when they can to minimise the chance of accidentally killing new timers by mistake. -1
is commonly mistaken to be the invalid ID - it isn't.
The function to be called must be public. That means it has to be forwarded.
